# Infrastructure as Code Best practices for managing cloud infrastructure declaratively with Terraform, Pulumi, CloudFormation, and OpenTofu. Covers module composition, state management, security scanning, and drift prevention. ## IaC Tool Comparison Choose the right tool based on team skills, cloud strategy, and operational requirements. | Tool | Language | State Management | Multi-Cloud | Learning Curve | Ecosystem | |------|----------|-----------------|-------------|----------------|-----------| | Terraform | HCL | Remote backend (S3, GCS, etc.) | Excellent | Medium | Largest provider ecosystem | | OpenTofu | HCL | Same as Terraform | Excellent | Medium | Fork-compatible with Terraform | | Pulumi | TypeScript, Python, Go, C# | Pulumi Cloud or self-managed | Excellent | Low for developers | Growing, SDK-based | | CloudFormation | YAML/JSON | AWS-managed | AWS only | Medium | Native AWS integration | | CDK | TypeScript, Python, Java, Go | AWS-managed (synths to CFN) | AWS only | Low for developers | Leverages CFN resources | | Decision Factor | Recommendation | |-----------------|---------------| | Multi-cloud required | Terraform or Pulumi | | AWS-only shop | CloudFormation or CDK | | Team knows TypeScript | Pulumi or CDK | | Need open-source license | OpenTofu | | Existing Terraform codebase | Stay Terraform or migrate to OpenTofu | | Complex logic and loops | Pulumi (general-purpose language) | ## State Management Patterns State is the source of truth for what IaC
